During the last Build conference all attendees were given a brand new sparkling exciting Surface RT device (I love that machine despite its name but that's beside the point). On it came a version of Office 2013 RT, or better: the preview version.
Now, I translated that term "Preview" to "Beta". Which is OK, since I've been using a lot of beta products from Microsoft and they all were great.
And then I wanted to post a blogposting from Word. I knew I could, I have been doing this for a long time (I prefer Live Writer but that isn't available on Windows 8 RT). So I wrote the entry and hit "Publish". Instead of my blogsite I got a nice non-descriptive error telling me I couldn't post. So I fired up my other (Intel based) Win8 tablet, opened Word RT Preview, it loaded my blogpost (you've got to love the automatic synchronization through Skydrive) and tried from that machine. Same error.
So, I installed Live Writer (remember, the other machine is Intel based) and posted from there. That worked like a charm.
Apparently, there was something wrong with Word. I gave up and didn't think about it anymore.
Yet… what you're reading now is written in Word 2013 RT on my Surface RT. So what did do? Simple: I updated from the Preview version to the final version. That's all there was to it.
So…. If you're still on the preview I urge you to upgrade. You need to go to the "classic desktop update" window instead of going through the Windows Store App style update since Office is a desktop system, but once you do that you'll have the full version as well.
